File and data protection strategies such as various RAID levels or snapshots can go only so far in protecting
data from loss, but ReadyNAS OS provides five separate strategies that work together to provide substantially
better protection than any one strategy.

The different levels of disk redundancy provided by RAID types provide degrees of file protection from the
loss of one or more disks, but cannot do anything about accidental deletion or corruption; can mask, but not
prevent, gradual corruption caused by the slow degradation of the disks; and cannot provide protection from
a site disaster. Snapshot technologies provide protection against accidental deletion or corruption but by
themselves cannot protect against disk loss or site loss.

ReadyNAS OS allows you to use five different types of protection simultaneously:

RAID. Protects against disk failure.

Snapshot technology. Protects against accidental data deletion or corruption by providing point-in-time
recovery.

Real-time antivirus. Protects against loss or corruption from viruses.

Bit rot protection. Protects against the degradation of data from disk aging.

Offsite backup. Protects against site loss.
